Below are links to resources for computer programming. The ability to read and write code is an essential 21st century skill and one that will be involved in MANY of our MAKER projects. Even if you aren't writing code from scratch, the ability to look at code and make tweaks based on sample code will allow you to add interest and excitement to your project. Sometimes something as simple as changing the color variables of someone's sample code can add great personalization to your project!
